(54)	Area mapped compressed image bit budget monitor

(57) An area mapped compressed bit budget monitor receives a compressed video signal that represents frames of a video signal broken down into blocks of pixels with each block being represented by a bit sequence. The bits in each bit sequence are counted to produce bit counts that are translated into color and intensity values. The color and intensity values are used to present an area mapped display, with each block of a displayed frame being outlined according to the associated color and intensity value, or the outline being alternatively filled by the associated color and intensity value. The area mapped display may also include a cursor in the form of a filled block together with an associated coefficient array for the block indicated by the cursor.
